How to make the Indicator write in the DESCRIPTION portion of the horizontal line it drew
Hi
You can use the function ObjectSetText(). Refer to:
https://docs.mql4.com/objects/ObjectSetText
Cheers
Jellybean
I tried adding in this indicator Objectsettext but it does not work. Where should I place it?

//| Description:
//| - Draws number of ppz lines specified by user. (num_ppz_show)
//| - Draws ppz with highest number of confulence first.
//| confulence is calcuated by how close to high/low of a bar (tolerance)
//| - PPz levels are at certain pips away from each other (ppz_spacing)
//| - programs runs at startup or at first 2 minute of time frame
//| work best at 4H & daily charts

Hi guys,
I have this code called Sweetspot gold that draws lines at every specific interval like 500 pips etc
It writes a Name at every horizontal line it draws
string linename= "[SweetSpot] " + text + " Line",
[SweetSpot] 1.6500 Line
Can this be written in the DESCRIPTION too?
